Abstract
The invention is directed to methods of neutralizing acid drainage from particulate mining waste, comprising consolidating the particulate mining waste to form a consolidated waste solid; adding a hydrophobizing material into the consolidated waste solid, and incorporating into the consolidated waste solid a controlled release base formulation, wherein the controlled release base formulation comprises a particulate base and a controlled release system, and wherein the controlled release base formulation responds to a decrease in pH from acid drainage to release the particulate base, thereby neutralizing the acid drainage.
